Curated OER
Absorbancy: What does it mean?
Define the scientific concept of absorbency as it relates to the properties of matter, then conduct an investigation. Learners answer several questions, then investigate the absorbency of several different types of towels. Tip: This...
Curated OER
To stretch or not to stretch
Hands-on is the best way to play. Learners read a graph that shows the force needed to stretch a rubber band. They do this and then participate in a simple experiment where they create coiled springs with wire. They work to determine how...
